My Samsung Galaxy 6 Edge+ intermittently has two icons I don't recognize in the upper left corner:

Numbering them 1 2 3 4 5 6 from the left, 2 means Screen Shot Taken, and 4, 5, and 6 I also understand. But numbers 1 and 3, I don't understand. Number 3 seems to be a Google app, since it includes what looks like a Google G. These two icons seem to come and go at random. They aren't in the Icon glossary in the phone's Help. Does anyone recognize them?
Related question: I already have the temperature displayed on another area of my home screen via a weather widget. I don't need it also up in the left (number 5.) But I can't figure out how to get rid of it there.
Thanks for any information.
